MT-2 (Melanotan 2 Acetate) 10vials/box

Basic Information

Full Name: Melanotan-2 Acetate

Sequence: Ac-Nle-cyclo [Asp-His-D-Phe-Arg-Trp-Lys]-NH₂ (Cyclic heptapeptide, C- terminal amidation)

CAS: 121062-08-6

Molecular Weight: ≈1024 Da

Dosage Form: Lyophilized Powder

Half-Life: ≈33 hours (Long-acting; daily or every-other-day dosing is sufficient)

II. Core Mechanism of Action (Multi-receptor activation)

MT-2 produces multiple effects by activating MC1R/MC3R/MC4R/MC5R, which is the source of its "one peptide, multiple effects":

MC1R (Skin)

Stimulates melanocytes to synthesize eumelanin (brownish-black), achieving tanning without sun exposure.

Enhances skin's resistance to UV rays, reducing the risk of sunburn.

MC3R/MC4R (Central)

Enhances libido and improves erection/sexual arousal (and...) PT-141 Homologous Pathway)

Suppresses appetite, reduces calorie intake, and aids in fat loss.

MC5R (Peripheral)

Regulates sebum secretion and hair pigmentation, affecting metabolism and immunity.

III. Core Efficacy (Scientific Research / Gray Market Applications)

1. No-Sun Tanning (Most Mainstream)

No sun exposure required; tanning begins in 7-10 days, reaching a plateau in 4-6 weeks.

Suitable for those who are difficult to tan or prone to sunburn, evens out skin tone.

Using a small amount of UV (sunbathing/tanning lamp) doubles the effect and makes it more natural.

2. Improved Sexual Function

Enhances libido, sexual arousal, and erectile hardness (men).

Improves female sexual arousal disorders, acting on the central nervous system rather than peripheral blood vessels.

3. Metabolism and Fat Loss

Suppresses appetite, reduces food intake, and lowers body fat percentage.

Mildly boosts metabolism and improves insulin sensitivity (scientific research data).

IV. Standard Usage and Dosage (Scientific Research Reference)

1. Reconstitution (Crucial)

Soluble: 0.9% Benzyl Alcohol Antibacterial Water (BAC Water)

Ratio: 10mg MT-2 +10mL BAC water = 1 mg/mL (1,000 mcg/mL)

Procedure: Pour along the side of the bottle, gently swirl to mix, do not shake vigorously.

Storage: Refrigerate at 2–8°C after reconstitution.
